Effect of freeze-thaw cycles on mechanical and porosity properties of recycled construction waste mixtures

To investigate the effect of freeze-thaw cycle on the mechanical and porosity properties of the recycled construction waste mixtures, a series of freeze-thaw cycles, cyclic loading and unloading and CT scan tests were carried out on four proportions of samples, including the brick, concrete and mortar slag. The testing results reveal that the strain presents a parabolic or linear increase with the increasing freeze-thaw cycles. Hence, the...
